    • A new class of poly(beta-amino alcohols) (PBAAs) has been prepared using combinatorial polymerization. The inventive PBAAs may be used in biotechnology and biomedical applications as coatings (such as coatings of films or multilayer films for medical devices or implants), additives, materials, excipients, non-biofouling agents, micropatterning agents, and cellular encapsulation agents. When used as surface coatings, these PBAAs elicited different levels of inflammation, both in vitro and in vivo, depending on their chemical structures. The large chemical diversity of this class of materials allowed us to identify polymer coatings that inhibit macrophage activation in vitro. Furthermore, these coatings reduce the recruitment of inflammatory cells, and reduce fibrosis, following the subcutaneous implantation of carboxylated polystyrene microparticles. These polymers may be used to form polyelectrolyte complex capsules for cell encapsulation. The invention may also have many other biological applications such as antimicrobial coatings, DNA or siRNA delivery, and stem cell tissue engineering.
    • 使用组合聚合制备了一类新的聚(β-氨基醇)(PBAAs)。 本发明的PBAAs可用于生物技术和生物医学应用中,作为涂层(例如用于医疗装置或植入物的膜或多层膜的涂层),添加剂,材料,赋形剂,非生物污垢剂,微图案化剂和细胞包封剂。 当用作表面涂层时,这些PBAAs根据其化学结构在体外和体内引起不同程度的炎症。 这类材料的大化学多样性使我们能够鉴定体外抑制巨噬细胞活化的聚合物涂层。 此外,在皮下植入羧化聚苯乙烯微粒之后,这些涂层减少了炎性细胞的募集,并减少了纤维化。 这些聚合物可用于形成用于细胞包封的聚电解质复合物胶囊。 本发明还可以具有许多其他生物学应用,例如抗微生物涂层,DNA或siRNA递送以及干细胞组织工程。
